Abstract:

The investigation of nanodevices with specific capacitive effects is one of the issues that must be addressed to develop the nanotechnology subject. In this paper we present by quantum mechanics calculations, the design of these properties of an organic three-terminal nanodevice, the controlled molecular rectifier (CMR). Our results are consistent with: (a) The capacitance shows increase for values lower and greater than a specific value (from −1.5 V and 0.9 V) provoking on switch state in the device without gate current; (b) diffusion [depletion] capacitance is present under forward and reverse [only reverse] bias; (c) a rectifier with asymmetric bi-directional bias is acquired; (d) also the CMR device has the same capacitive properties of usual thyristor family and Schottky diode integrated in a single device. The CMR could be utilized as a device that works at low potency level and high operational frequencies as PHz, e.g., 1012 times higher than typical devices and it could be useful for applications in switches that demand high-speed static pulse signals.
